Is my ISA account with IBKR a flexible ISA?

Interactive Brokers (U.K.) Limited (IBUKL) only offers stocks and shares ISAs (including, Junior Stocks and Shares ISAs).

IBUKL does not offer cash ISAs (including, Junior cash ISA) or flexible ISAs (including, Junior flexible ISA). A flexible ISA means you can take money out, but it will count towards your annual ISA allowance if you pay it back in the same tax year. QROPs (Qualified Recognised Overseas Pension Schemes) and PRSAs (Personal Retirement Saving Accounts) are also not supported…

You are free to withdraw funds from the ISA account to your personal bank account.

Note…

Tax year runs from 6 April to the following 5 April. Each tax year’s ISA subscription limit is specific to that year and can be checked on the HMRC website. 

For the 2023/24 tax year the annual ISA allowance is £20,000 per person. Any of the ISA allowance that goes unused in the current tax year cannot be rolled over to the subsequent tax year. You can divide this cash allowance across multiple ISAs, provided that not more than 1 of each type of ISA is subscribed to in any given tax year…

A flexible stocks and shares ISA allows the individual to withdraw funds from their stocks and shares ISA and put them back into it, within the same tax year, without affecting their annual ISA allowance…
